Common Causes

When your Honda Accord's brake lights stay on, it can be frustrating and potentially drain your battery. The most common causes include:

  • Faulty brake light switch: The switch that activates your brake lights may be stuck in the "on" position.
  • Missing or broken brake pedal stopper: A small rubber piece that helps depress the brake light switch may have fallen off or disintegrated.
  • Electrical issues: Wiring problems or a faulty fuse can cause the brake lights to remain on.

Brake Pedal Stopper

The most frequent culprit is a missing or broken brake pedal stopper. This small rubber piece is crucial for proper brake light function. To check and fix this issue:

1. Look under the dashboard near the brake pedal.

2. Check for small blue plastic pieces on the floor, which may be remnants of the broken stopper.

3. If missing, replace the stopper (Honda part #46505-SA5-000) or use a temporary fix like a coin or small bolt.

Brake Light Switch

If the stopper is intact, the brake light switch might be the problem. To inspect and potentially fix the switch:

1. Locate the switch near the top of the brake pedal.

2. Check if the switch plunger is stuck in the depressed position.

3. Try adjusting the switch position by loosening its mounting nut.

4. If adjusting doesn't work, you may need to replace the switch.

Electrical Issues

If neither the stopper nor the switch is the problem, electrical issues may be to blame. Check the following:

  • Fuses: Inspect the brake light fuse in the fuse box.
  • Wiring: Look for any visible damage to the wiring near the brake pedal or tail lights.
  • Brake light failure sensor: This component may be malfunctioning.

Temporary Solutions

While waiting for a permanent fix, you can try these temporary solutions:

  • Remove brake light fuse: This prevents battery drain but is not a long-term solution.
  • Disconnect brake light switch: Unplug the electrical connector to the switch.

Remember: Driving without functioning brake lights is illegal and dangerous. Fix the issue as soon as possible.

Professional Help

If you're uncomfortable performing these checks or repairs, it's best to consult a professional mechanic. They can diagnose and fix the issue safely and efficiently.
